P12 = Alarm 2 operating mode

Available only when P11 is equal to "AL2.P", "AL2.b" or "AL2.d".

H.A. = High alarm (outside for band alarm) with automatic reset (latched).

L.A. = Low alarm (inside for band alarm) with automatic reset (latched).

H.L. = High alarm (outside band) with manual reset (latched).

L.L.= low alarm (inside band) with manual reset (latched).

P13 = Programmability of the alarm 2 threshold and hysteresis values

Available only when P11 is equal to "AL2.P", "AL2.b" or "AL2.d".

OPrt = Alarm 2 threshold and hysteresis are programmable in the operating mode.

COnF = Alarm 2 threshold and hysteresis are programmable in configuration mode.

P14 = Alarm 2 threshold value

Available only when P11 is equal to "AL2.P", "AL2.b" or "AL2.d" and P13 is equal to "COnF". Range: For process alarm - within the range

limits.

For band alarm - from 0 to 500 units. For deviation alarm - from -500 to 500 units.

P15 = Alarm 2 hysteresis value

Available only when P11 is equal to "AL2.P", "AL2.b" or "AL2.d" and P13 is equal to "COnF". Range: from 0.1% to 10.0 % of the range selected

with P3 and P4 parameters, or 1 LSD.

P16 = Threshold of the “Soft Start” function. Threshold value in eng. units to initiate the "Soft start" function (output power limiting) at start up. Range : within the readout span.

NOTE: This threshold value will not be taken into account when tOL = InF.

P17 = Safety lock

0 = No parameter protection. The device is always in unlock condition and all parameters can be modified.

1 = The device is always in lock condition and no one of the parameters (exception made for set points [SP, SP2] and manual reset of the alarms) can be modified (for SMART status see P30 parameter).

From 2 to 4999 = This combination number is a secret value to be used, in run time (see nnn parameter) to put the device in lock/unlock condition.

For SP, SP2 and manual reset of the alarms, the lock/unlock condition has no effect (for SMART status see P30).

From 5000 to 9999 = This combination number is a secret value to be used, in run time (see

nnnparameter) to put the device in lock/ unlock condition.

For SP, SP2, manual reset of the alarm, AL1, AL2, the lock/unlock condition has no effect (for SMART status see P30).

NOTE:when safety lock is selected, the secret value can not be displayed again and the display will show 0, 1, SFt.A (when P17 is encompassed between 2 and 4999) or SFt.b (when P17 is encompassed between 5000 and 9999)
